i;"-i1`l'iis-invention relates to improvements in trolley-Wheels and supports. The,objectoftheinvention is to provide a 15 dev-ice othis character oom rising a support having formed in one en anl 'adjustable socket to receive the upper end of tbe trolley4 pole yand on its opposite end with a pivotailymounted forked bearingbraoiret to receive zo the trolieyevbeel.

Another object is to provide a trolley Wbeel'f'orined in sections and means whereby said sections oi" the wheel are removably secured to a shaft, which is revolubly mounted 254 in Said forked bracket.

A further object is to provide a detachable connection for the upper end of the electrical conductor or cable.

With the above and other objects'in View 3o the invention consists of certain novel fea-- tures of construction., combination, and arrangement oparts, as Will be hereinafter cle- Seribed and claimed.

in the accompanying drawings, Figure 1 ie 3 5 a side View oi a trolley-wiieel and support constructed in accordance with the inven tion, parte oiv the same being shown in eee tion. Fig. 2 is an edge Vewoi' the Same. Fig. 3 is an irregular sectional View on the Fig. i is a seotionai View View on tbnfiine 5 5 in Fig. 1. r

Referring more particularly tothe drawings, 1 denotes the support, the ioWer end or' 4 5 which is formed with a tapered socket 2. In

two or the opposite sides of seid soeketed. end

of the support are forme-ci slits 3, whereby said end of the support may be adjustabiy 'clamped to the upper end of tile troiieywpole 5o by means of a clampingbolt fi, thereby perrnitting the Wearing or shrinking of the upper end ofthe pcie to be' compensated for.

Eevolubiy mounted upon the epinf die 5 is. forked bearingybracket 7, said ythereby preventing the removal of the bracket 2. On tbe opposite sides of the con neeted portions oi each. section of the bracket are formed lsrteraiiy-nrojecting epertured ears or iugs, through winch are adapted to be paseeri bolts 12, by means of which the sections of the brackets are secured together.

in the u per'iorked ends of the brackets 7 are forme alineci ,bearingepertures 13, in which are arranged. bushings 14..' in the bufsiiings 14 are gournaled the opposite reduced ends of e 5ba-tit 15, the enlarged portion or' said shaft being tiueaded,'as shown at 1,`an i on said tirrearied is aflapterl to be screwed e trolley-wheei 17. Said. Wheel is here shown andis preferably eonstruetefl in three sections, a central seotion 18, Jforming an ing surface for the trolley-Wire, and two outer eide sections 19,

forming tbe iianges oi 'tbe wheel. By thuseonstructing the Wheel either of Seid sections when beconnny worn may be readily .removed and. rep aeed by a new seetlon. On

the edges or the forks oi-tbe bracket 7 are arrangeil oil-oups 2t), which ooinmunicate with "it-an gul ariyfproi eeting bearingespindle 5 ,v

Arrangedl on one side of the support 1 is a cable-attaching device, by which the upper end of an electr-ical cable lor conductor is secured to the su port. The connection here shown is in the orm of a sleeve or ferrule 22, on which is formed a right-angularly-projectingthreaded shank 23, which is adapted to be screwed into a threaded aperture formed in the side oi' the socket, as shown.

A trolley-wheel and support Constructed kas herein shown and described will be found to' possess niany advantages over the comrnon form of device, and by forming 'the trolley-wheel of separate detachable sections the same may be kept in perfect working order.

From the foregoing description, taken in connection with ythe accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion,

and the minor details of construction may be resorted to without departingr from the prinl ciple or sacrificing any of the advantages'of thls invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

-In a device of the character described, the 'combination with a Wheel-support having formed in one end a s lit ta, ering socket to receive the end of a trolley-p le, or" a bearingspindle arranged'on the upper end of said support, said spindle having formed therein annular grooves, a sectional, forked bearingbracket pivotally mounted on said spindle, said bracket having formed thereon annular flanges to engage the annular grooves in said spindle, means to removably secure said vsectlons of the bracket together, a shaft journaled in saidV bracket, a sectional trolley- Wheel arranged on said shaft, and Ineans wherebythe sections of said wheel are removably connected to the shaft, substantially as described.

In testimony Whereoi` We have hereunto set our hands in presenceof two subscribing witnesses.
